In an indexing mechanism as described in Specification 1,006,014, the locating means comprises a lever arm 178 mounted at a pivot 180 and carries an index finger 182 having a curved locator surface 184 which has its centre of curvature at the pivot axis of the arm 178. The surface 184 has, therefore, line contact with the surface 174 of the recesses 172 and effects exact location irrespective of the width of the recesses since the finger merely moves into the recess to a greater depth without affecting the location of the plate. The finger 182 is removably mounted on the arm 178 and in order to provide contact with the surface 174 at different parts, fingers of different radial spacing between surfaces 184 and 186 are provided and are retained in place by set-screws 190. This in effect varies the length of the radius R.

[Also in Division B8] Apparatus for loading containers on and discharging containers from a vessel 17 comprises two separately movable, similar structures 10, 30 shown aligned in Fig. 1 and connected by bridging pieces 34. The unit 10 which can move along rails 13, has two straight parallel lengths of track 15, 16 for carriages 23, interconnected by a movable curved bridging section 25. The apparatus in this embodiment thus provides an endless track along which the carriages 23, each with a hoisting mechanism, can travel unidirectionally in succession. The bridging piece 25 can be moved along the tracks 15, 16 so as to position a carriage 23 correctly over the vessel 17. The outer section of the track is pivoted at 19 so that it can be raised out of the way of a vessel 17 as it berths or sails. Fig. 2 shows that a carriage 23 is carried on track 15 or 16 on a set of wheels 22 running on a rail 21, a second set of wheels 26 is provided to engage the track on the curved bridging section 25 and, as the latter is sloped up away from the rail 21 the wheels 22 are lifted from that rail to enable the carriage 23 to pass on to the bridging section 25. Each carriage has two motors (45), (46), Fig. 5 (not shown), and when both are operated the load is lifted at full speed while with only one motor running the load is hoisted at half speed. The carriages 23 may be controlled from a single control station by an operator, or each carriage may carry its own operator. Fig. 3 shows a modification of the above arrangement wherein carriages 23 can travel along a track 66 fixed on the quayside on to portions of track 68, 62, 64, 63, 65 and back on to track 66, returning along a track 67, structure 60 being itself movable along the quayside. Loading and unloading may proceed simultaneously and two ships, one on each side of a pier or jetty may also be dealt with simultaneously. Cargo may also be transferred between the vessel 17 and a lighter moored alongside (not shown).

The torque imparted to assembly 34, 35, by clock spring 50, is at least sufficient to counterbalance the weight of the unoccupied seat 12. When the seat 12 is occupied, the adjustment means may be automatically locked. Parts 16, 21, 28, 34, 35 and 40 are made of nylon, parts 16 and 21 may, alternatively, be made of acetal resin.

A coke oven door 10 having latch bars adapted to engage hooks on the door frame, and flexible diaphragms acting through a fluid medium to exert pressure forcing the bars against the hooks, has means for reducing this pressure when the door is lifted for removal. The means comprises a diaphragm 24 connected by pipes with the other diaphragms and mounted at the centre of the door and acting against a spring 29 arranged about a pin 26 which has a slot 27 which receives an arm (43) on a bar 41 of a lever system (37 ... 40), see Fig. 6 (not shown). The door lifting lug (35) is connected to the levers so that on raising the lug, which is permitted a small vertical movement relative to the door, the levers rotate the arm (43) about a horizontal axis to move the pin 26 and plate 25 outwards against the spring 29 and reduce pressure in the diaphragm 24 and so in the other diaphragms. The pressure in the diaphragm 24 may be adjusted by nuts 34.

Abstract: 1,228,106. Tipping vehicles. OVERUMS BRUK A.B. 30 May, 1969 [30 May, 1968], No. 27499/69. Heading B7B. [Also in Division B8] A vehicle for detachably supporting a container A comprises a U-shaped frame 1 open at the rear with a carrying member 4, also U-shaped, movably disposed thereon. Pivoted rigid links 6 connect the frame 1 and the rear of the member 4 and two hydraulic rams 5 are pivoted between the frame 1 and the forward end of the member 4. In operation, with the member 4 in a lowered position, Fig. 1 (not shown), the vehicle is reversed so that the limbs of the frame 1 and member 4 straddle the container A standing on the ground. Operation of the rams 5 causes the member 4 to engage carrying rails B on the container A and raise it to the full-line position shown in Fig. 4. The rear of the frame 4 is then supported by a pair of self-locking articulated links 7 and the front by two struts 10. The rams 5 are thus relieved during transport. The contents of the container A can be discharged through a gate 13 on tilting the container A by further actuation of the rams 5 to the chain-dot position shown in Fig. 4. When the container A is to be lowered retraction of the rams 5 pivots the container A about pins 8 causing projections 14 to abut the articulated links 7 so that they fold out of their self-locking position.

Abstract: 1,228,412. Gain control; transistor switching circuit. BRITISH BROADCASTING CORP. 12 March, 1969 [5 March, 1968], No. 10706/68. Headings H3T and H4N. A fader X, Fig. 1, comprises a series resistor 21 connected to an input terminal 11 and feeding the drain-source path of a F.E.T. 10, connected to an output terminal 12, with the collector emitter path of a junction transistor 30 connected in shunt across the signal path between the drain of the FET and signal earth. Control voltage is applied to the gate of the F.E.T. and the base of the junction transistor to differentially vary their impedances. The arrangement reduces the effect of the source drain capacitance at high attenuation settings of the fader, preventing cross-talk. The junction transistor 30 may be provided with negative feed-back from emitter to collector by a further transistor (31) Fig. 2 (not shown), to provide a lower impedance shunt path. In addition the potential controlling the impedance of the shunt transistor 30 may be derived from the drain source voltage of the F.E.T., e.g. from the drain, since the terminal 14 is connected to a virtual earth at the low impedance input of amplifier 17.
